A design method for nanofluidic circuits

A design method is proposed for nanofluidic circuits, based on the flow equation for a nanoscale fluid flow. This method incorporates the use of the concepts of the flow resistance, the flow rate, the pressure drop and the power loss, as like in electric circuits. The equations for calculating the flow resistance and the power loss in exemplary nanofluidic circuits including in a nanotube tree are presented. It was found that the nanotube size and the fluid-tube wall interaction both have great influences on the flow resistance and the power loss in nanochannel flow. Exemplary design analysis is given for some nanofluidic circuits, based on the proposed method.
